    Characterizing user access to videos on the World Wide Web1999Inngår i: Multimedia computing and networking 2000 / [ed] Klara Nahrstedt, Bellingham, Wash: SPIE - International Society for Optical Engineering, 1999, s. 130-141Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Despite evidence of rising popularity of video on the web (or VOW), little is known about how users access video. However, such a characterization can greatly benefit the design of multimedia systems such as web video proxies and VOW servers. Hence, this paper presents an analysis of trace data obtained from an ongoing VOW experiment in Lulea University of Technology, Sweden. This experiment is unique as video material is distributed over a high bandwidth network allowing users to make access decisions without the network being a major factor. Our analysis revealed a number of interesting discoveries regarding user VOW access. For example, accesses display high temporal locality: several requests for the same video title often occur within a short time span. Accesses also exhibited spatial locality of reference whereby a small number of machines accounted for a large number of overall requests. Another finding was a browsing pattern where users preview the initial portion of a video to find out if they are interested. If they like it, they continue watching, otherwise they halt it. This pattern suggests that caching the first several minutes of video data should prove effective. Lastly, the analysis shows that, contrary to previous studies, ranking of video titles by popularity did not fit a Zipfian distribution.

    User toolkits for citizen-centric mobild service innovation2012Inngår i: eChallenges e-2012 Conference Proceedings / [ed] Paul Cunningham; Miriam Cunningham, IIMC International Information Management Corporation , 2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Around the world, there is an ongoing shift from en economy focusing on product development to an economy with focus on digital service development. An ongoing initiative in Europe to support this shift is the Internet of Services (IoS) which strives for a situation where everything that is needed to use a software is available as a service. The aim of this paper is to present a toolkit that non-programmers can use develop their own innovative mobile services. This environment strives to put forth a situation where technologies are made available as components that easily can be composed into a mobile services by just about anyone. This has tremendous impact on the feasibility of citizen-centric services where citizens create apps based on their current needs in their contemporary situation.

    Wearable systems in nursing home care: prototyping experience2006Inngår i: IEEE pervasive computing, ISSN 1536-1268, E-ISSN 1558-2590, Vol. 5, nr 1, s. 86-91Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The development of a wearable prototype systems after studies conducted in a nursing home care is discussed. The specific problems encountered by medical workers at nursing homes includes communication, information dissemination, access to patient charts and organizational issues. The failure of which may cause stress, discomfort, and dissatisfaction among caretakers and patients as well as possible detrimental health consequences for patients. A Wizard of Oz experiments was used to retrieve information, process interrupting phone calls, to simplify communication with others, and to minimize the interaction needed with the wearable computer.

    Relieving the medical workers' daily work through wearable and pervasive computing2005Inngår i: ICE2005: the 11th International Conference on Concurrent Enterprising : integrated engineering of products, services and organisations, Munich, Germany 20-22 June 2005, Nottingham: Centre for concurrent enterprising, University of Nottongham , 2005Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We intend to relieve the daily work at care-centers, allowing medical workers to focus on the patients and their needs. This goal can be achieved by employing technology that automate and simplify tasks previously requiring tedious interventions, giving more time for the important human to human interaction. For any technology to become accepted by the medical workers, we must ensure that it is highly natural and unobtrusive, without interfering with their caregiving. By studying the medical workers’ daily work, we can draw conclusions on what problems they encounter, allowing us to develop prototypes which can be deployed and used at the care-centers. In doing this, we can proceed to study the acceptance and usability of our proposed solution, and see whether and how it solves the problem. In this position paper, we present our current and future research in wearable and pervasive health-care.

    Experiences from mobile e-meetings with the borderland wearable computer2003Rapport (Annet vitenskapelig)
    Abstract [en]

    People are presented with an increasing number of opportunities to communicate regardless of location as wireless network connectivity becomes more prevalent. Questions that arise are in what form this communication is and what challenges it poses? Can the experience of group communication be enhanced so that a feeling of actual presence can be conveyed? Can we enable participants to experience the world from another person's perspective? We believe so, in this paper we discuss our experiences of group communication when using a wearable computer that is always connected to the network.

    Experiences of conveying knowledge in borderland2003Rapport (Annet vitenskapelig)
    Abstract [en]

    One of humankind's most basic needs is that of being able to communicate with other people. As wireless network connectivity becomes more prevalent, factors such as physical location and situation diminish in significance for deciding when and how such communication can take place. What happens when a user is given this freedom to utilize the network regardless of time and place? Questions that arise are how different media can enrich communication and what challenges it poses. Can we enable other users to experience the world from another person's perspective? Can we expand it beyond pure communication and allow other more novel uses to emerge? Can we use this as a way of conveying knowledge in real-time to those in need of it? We believe so, in this paper we discuss our experiences of mobile communication when using a wearable computer that is always connected to the best network available.

    Methods for interrupting a wearable computer user2004Inngår i: Proceedings: Eighth IEEE International Symposium on Wearable Computers, ISWC 2004 : 31 October - 3 November 2004, Arlington, Virginia, Los Alamitos, Calif: IEEE Communications Society, 2004, s. 150-157Konferansepaper (Fagfellevurdert)
    Abstract [en]

    A wearable computer equipped with a head-mounted display allows its user to receive notifications and advice that is readily visible in her field of view. While needless interruption of the user should be avoided, there are times when the information is of such importance that it must demand the user’s attention. As the user is mobile and likely interacts with the real world when these situations occur, it is important to know in what way the user can be notified without increasing her cognitive workload more than necessary. To investigate ways of presenting information without increasing the cognitive workload of the recipient, an experiment was performed testing different approaches. The experiment described in this paper is based on an existing study of interruption of people in human-computer interaction, but our focus is instead on finding out how this applies to wearable computer users engaged in real world tasks.

    Experiences of using wearable computers for ambient telepresence and remote interaction2004Inngår i: Proceedings of the ACM SIGMM 2004 workshop on effective telepresence ETP 2004: Toward seamless remote interaction and experience, IEEE Communications Society, 2004, s. 2-11Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present our experiences of using wearable computers for providing an ambient form of telepresence to members of an e-meeting. Using a continuously running e-meeting session as a testbed for formal and informal studies and observations, this form of telepresence can be investigated from the perspective of remote and local participants alike. Based on actual experiences in real-life scenarios, we point out the key issues that prohibit the remote interaction from being entirely seamless, and follow up with suggestions on how those problems can be resolved or alleviated. Furthermore, we evaluate our system with respect to overall usability and the different means for an end-user to experience the remote world

    Abstract [en]

    Traditionally, interaction methods for wearable computers have focused on input to the computer itself, yet little has been done when it comes to allowing interaction with the surrounding environment. Pervasive computing, on the other hand, offers access to computational power from any place all the time, yet most interaction techniques utilize either physical hardware or monitoring of the user in order to receive input. This paper presents a novel form of interaction by which a wearable computer user can interact with and control a pervasive computing environment in a natural and intuitive manner. Using sensors, the user can be allowed to literally "throw" events into the environment as a way of interacting with devices and computers

    Using the "HotWire'' to study interruptions in wearable computing primary tasks2006Inngår i: Proceedings: Tenth IEEE International Symposium on Wearable Computers, ISWC 2006 : Montreux, Switzerland, October 11 - 14, 2006, Piscataway, NJ: IEEE Communications Society, 2006, s. 37-44Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As users of wearable computers are often involved in real-world tasks of critical nature, the management and handling of interruptions is crucial for efficient interaction and task performance. We present a study about the impact that different methods for interruption have on those users, to determine how interruptions should be handled. The study is performed using an apparatus called "HotWire" for simulating primary tasks in a laboratory experiment, while retaining the properties of wearable computers being used in mobile, physical, and practical tasks.

    A configurable transport layer as a cure for crying babies2001Inngår i: CSEE'2001: Conference Proceedings, Luleå tekniska universitet, 2001Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Group collaboration and media distribution ap- plications have attracted more interest during recent years. With an increasing attention to wireless environments and business applications there is a growing need for reliable multicast communication protocols. There have been mainly two approaches, proactive or re- active, to error handling in reliable multicast. Proactive protocols transmit redundant information along with the original information, enabling the receivers to repair lost packets without the necessity of feedback to the sender. Re- active protocols rely either on positive or negative feedback from the receivers. A case of special interest in relation to wireless connec- tivity is where essentially one receiver on a lossy link even- tually will consume most of the error handling resources. This problem has been addressed by some researchers, e.g. by the use of probabilistic methods. We propose to view reliable multicast as a special case of semantically reliable multicast. We propose to make use of the application’s knowledge of its specific semantics to improve e.g. on the problem with single, lossy, links. We suggest the design of a semantic rule set for the transport layer protocol, which can be configured by the application. Using application semantics would allow the application to relax the reliability requirement at the transport level.

    A literature review of recent developments in reliable multicast error handling2001Rapport (Annet vitenskapelig)
    Abstract [en]

    As the number of applications directed towards group collaboration and group media dissemination increases, the interest for multicast protocols has also grown during recent years. Several applications have a need for reliability. This is true for the use of shared network editors, shared white-boards, networked games, etc. An increased popularity of media and application distribution over the Internet and the beginning growth of mobile computing with its inherent inhomogeneity and higher loss-rate, will create a demand for security which will increase the need for reliable transmissions. This paper aims to study reliable multicast protocols from an error correction perspective. During recent years, a number of protocols have been proposed. The reliability properties of these lies partly with error correction measures, but to a great extent also with different topological and timing measures which are aimed at boosting protocol efficiency. As it turns out, there are mainly two groups of error correction measures which are used. They can be divided into reactive measures, and proactive. The development in this field of research is very fast. Although a number of studies have already been done, this paper aims to summarise the most recent developments in the area of reliable multicast. This is a literature study and the sources are mainly English-language references from the INSPEC database and the ACM, IEEE, and IEEE Computer Society's digital libraries, essentially from 1997 until 2000.

    Applying semantic reliability concepts to multicast information messaging in wireless networks2002Inngår i: IRMA Conference Proceedings: Issues & Trends of Information Technology Management in Contemporary Organizations / [ed] M. Khosrowpour, Hershey, Pa: Idea Group Publishing, 2002Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Public use of the Internet increases and applications suitable for multicast distribution grow more popular. An increasing percentage of users require wireless connectivity. Multicast solutions must therefore be able to handle receiver and network link heterogeneity. This paper proposes an approach to handle such challenges. According to a definition of semantic reliability, the reliability concept can be interpreted in terms of application semantics. By using semantic reliability traditional reliability constraints can be relaxed. Our approach is to use an application – transport layer communication to implement a dynamically configurable transport layer protocol whose error-handling rule set can be configured from the application or even from the sender in-session. It can also be initiated from the sender when the session starts.

    Applying user-behavior to bandwidth adaptations in collaborative workspace applications and video conferencing2003Rapport (Annet vitenskapelig)
    Abstract [en]

    A bandwidth-sharing scheme for group video conferencing is presented in this paper. The key features of the scheme are the monitoring of user behavior and message passing, which are used by each client in order to identify and report their interest in other group members. Each video sender operates on the information about other users ' interest in order to adjust the sender's own frame rate, resolution, and ultimately bandwidth consumption in an attempt to satisfy the current interests of the receivers as well as the overall bandwidth constraints of the session. A general framework, an initial prototype, and a bandwidth allocation algorithm are presented together with experimental results. The experiences from the prototype have prompted refinements to the bandwidth-allocation algorithm that will be important for future implementations. We also conclude that the necessary messaging will not add a significant amount of bandwidth.

    Schemes for user-interest controlled video bandwidth adaptation in a collaborative workspace environment2004Inngår i: 2004 IEEE International Conference on Multimedia and Expo, Piscataway, NJ: IEEE Communications Society, 2004, s. 197-200Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper, bandwidth-sharing schemes, controlled by user-interest, are presented as an approach to efficient use of resources in a collaborative workspace environment. Two schemes for group videoconferencing are presented and evaluated. Monitoring of user-behavior and message passing to adapt video bandwidth allocation to user needs are key features of both schemes, in which each user's client reports interest in other users to enable them to determine their relative importance. Experimental results using a prototype implementation to sample user-behavior show that one scheme is better suited for high, and the other for low bandwidth-limit scenarios. Measurements also show that the message passing does not add a substantial amount of bandwidth.

    Makerspace in school: Considerations from a large-scale national testbed2018Inngår i: International Journal of Child-Computer Interaction, ISSN 2212-8689, E-ISSN 2212-8697, Vol. 16, s. 9-15Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Digital fabrication and making has received a growing interest in formal and informal learning environments. However, many of these initiatives often start from a grassroots perspective, with little coordination on a national level. This paper illustrates and discusses a study from an ongoing large-scale national testbed in Sweden named Makerspace in schools (Makerskola). The project embodies a series of considerations that arise when a maker approach is applied to a geographically widespread national education context. The results of this study are based on an analysis of the extensive project documentation and first-hand experiences from initiating and running a large-scale national testbed in Sweden, involving more than 30 formal actors and more than one thousand active partners in a national educational setting. The main contribution of this paper is the identification and discussion of five different considerations that have emerged during the project, and include Procurement practices, The teacher and leader perspective, Informing national policy making, Creating equal opportunities, and Progression in digital fabrication.

    Shared mediated workspaces2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Shared mediated spaces provide viable alternatives for meetings and interactions. The development of collaborative mediated workspaces and shared negotiation spaces will have a fundamental impact on all human practices. Previous design-led research, has identified spatial design concepts, such as mediated gaze, and spatial montage, which, if unaddressed, may be said to impose friction, and thus impact negatively on the experience of mediated presence. The current paper discusses a set of conceptual tools for presence design, in relation to a prototype that is currently being developed by an interdisciplinary academic work group: The Mediated Sketching Table. The prototype combines analogue and digital interaction tools and technologies including HTML5 and WebRTC. Here, we present our initial observations when using the prototype and discuss possible ways to overcome design friction in the prototype. We acknowledge that mediated presence cannot be ensured by design or technology alone. However, by monitoring various design features, presence designers can seek to reduce the friction that otherwise inhibits mediated presence, mutual trust, knowledgesharing, and teamwork efficiency.

    Abstract [sv]

    Från ansökan: "Projektet skall via användarmedverkan, med skolungdomar och lärare på Tunaskolan i Luleå, kombinerat med smart IT och design av nya innovativa sätt för visualisering utveckla nya metoder för att minska energiförbrukningen. Projektet bygger vidare på resultat och samarbeten med både nationella och internationella EU projekt inom området energibesparing med fokus på användarmedverkan.Vi vill tillsammans med skolungdomar, morgondagens beslutsfattare, och via deras "normala" kommunikationsvägar (Internet, Web 2.0, Facebook etc) sprida och engagera om energi och miljö. Genom att bygga demonstratorer vill vi lära oss hur och vad man bör fokusera på för att både spara energi men även bidra till en större medvetenhet för områdena. Vi vet att ungdomar idag mycket snabbare sprider "god" information och huvudfokus för projektet är att tillsammans med ungdomarna förstå vad och på vilket sätt energiutnyttjandet skall visualiseras för att "nå ut" och spridas.Vårt mål är att engagera skolan, elever, lärare och besökare, till att bidra med idéer för hur man kan spara energi och värna om miljön. Tillsammans med projektdeltagarna kommer nya Internet-baserade applikationer attutvecklas för visualisering av i realtid uppmätt energiutnyttjande. Tillvägagångssättet kommer vara baserat på att genom korta och snabba iterationer sätta nya versioner av de utvecklade applikationerna "i händerna" påungdomarna som varit med och designat själva hur applikationerna ska se ut för att presentera energiförbrukning på ett enkelt sätt.Vi avser också att via medverkande företag, baserat på resultat i projektet, utveckla nya affärer och vi kommer kontinuerligt under projektet att sprida information om framsteg via Internet, konferenser samt andra samarbetsprojekt.

    Introducing Programming and Digital Competence in Swedish K-9 Education2017Inngår i: Informatics in Schools: Focus on Learning Programming. ISSEP 2017 / [ed] Valentina Dagienė, Arto Hellas, Cham: Springer, 2017, s. 117-128Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The role of computer science and IT in Swedish schools has varied throughout the years. In fall 2014, the Swedish government gave the National Agency for Education (Skolverket) the task of preparing a proposal for K–9 education on how to better address the competences required in a digitalized society. In June 2016, Skolverket handed over a proposal introducing digital competence and programming as interdisciplinary traits, also providing explicit formulations in subjects such as mathematics (programming, algorithms and problem-solving), technology (controlling physical artifacts) and social sciences (fostering aware and critical citizens in a digital society). In March 2017, the government approved the new curriculum, which needs to be implemented by fall 2018 at the latest. We present the new K–9 curriculum and put it in a historical context. We also describe and analyze the process of developing the revised curriculum, and discuss some initiatives for how to implement the changes.

    Abstract [en]

    Computing is no longer considered a subject area only relevant for a narrow group of professionals, but rather as a vital part of general education that should be available to all children and youth. Since making changes to national curricula takes time, people are trying to find other ways of introducing children and youth to computing. In Sweden, several current initiatives by researchers and teachers aim at finding ways of working with computing within the current curriculum. In this paper we present case studies based on a selection of these initiatives from four major regions in Sweden and based on these case studies we present our ideas for how to move forward on introducing computational thinking on a larger scale in Swedish education.

    An architecture for location aware applications2002Inngår i: Proceedings of the 35th Annual Hawaii International Conference on System Sciences: 7 - 10 January 2001 [i.e. 2002], Big Island, Hawaii / [ed] Ralph H. Sprague, Los Alamitos, Calif: IEEE Communications Society, 2002, s. 3805-3810Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents an architecture for location aware applications, where positioning sources such as GPS, WaveLAN and Bluetooth devices can be seamlessly interchanged and combined to achieve a more accurate positioning service with a higher availability. The architecture also supports peer-to-peer communication to allow clients to interchange position information over a network such as Bluetooth or WaveLAN. This enables a user to use other users position sources if their clients are close enough. The position information can be used directly by an application or be combined with habitual and other contextual information to achieve more personalized applications. A generic positioning protocol for interchange of position information between position sources and client applications, and different techniques for merging of position information are presented. The interfaces to the platform are also discussed. The paper finally touches on privacy issues and outlines a schema for handling positioning information by user controlled contracts

    Makerspaces Across Settings: Didactic Design for Programming in Formal and Informal Teacher Education in the Nordic Countries2018Inngår i: Journal of Digital Learning in Teacher Education, ISSN 2153-2974, Vol. 34, nr 1, s. 18-30Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For education to provide knowledge reflecting our current and future society, many countries are revising their curricula, including a vivid discussion on digital competence, programming and computational thinking. This article builds an understanding of the maker movement in relation to education in programming, by demonstrating challenges and possibilities in the interface between Makerspaces and teacher education. Three different Nordic initiatives are presented and their designs for learning are analysed. The article illustrates how Makerspaces and teacher education can be transformed by each other; how Makerspaces can be used in programming activities and what challenges and possibilities emerge in the meeting between the two. The results highlight a core aspect of the maker movement: authenticity. Designs for learning have different levels of authenticity, but in all cases authenticity has been a positive factor. These hands-on learning environments are designed to foster collaboration, share ideas and innovation with people from different backgrounds to transform and form multimodal representations together. In the interface between the formal and informal a potential for inclusion and creation of spaces that reach individuals from different backgrounds is found. Mobile learning is a phenomenon that the making movement together with teacher education can make use of, at for example practice schools, university campuses, mobile Makerspaces or “open-door”-approaches. In the digital environment learning is distributed, but collaboration between formal and informal education is so far complicated to establish, meaning that the academy needs to find more creative and flexible ways of making connections outside the academy.

    Connected media and presence2013Inngår i: Proceedings of the 2nd International Workshop on Socially-Aware Multimedia, Co-located with ACM Multimedia 2013: SAM '13, ACM Digital Library, 2013, s. 43-48Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Effective design of shared mediated spaces, information and connectedness requires theory and practice from a range of disciplines such as found in European projects like Together Anywhere, Together Anytime (TA2) and the EIT ICT Labs Mediating Presence activity. Building on this work we continue to investigate the changes in the European digital media industry such as changed traditional distribution of media content and the progressive integration of (social) communication means in information distribution and shared mediated spaces. Our past research has given valuable insights in how to design and evaluate systems and services that provide a high quality of experience, in how trust is established in mediated environments, and how the formation of tacit communication between participants in new distributed and connected media is negotiated. In the new Seventh Framework Program project COnnected Media and Presence from European Institute of Technology (COMPEIT) we aim to enhance the quality of experience in face-to-face and broadcast communication further in three domains: 1) Spatial connectedness, 2) Social connectedness and 3) Information connectedness, by developing three key services: Shared Experience with Tangible Interaction (SETI); Broadcast Presence Studio (BPS) and Mixed-Reality Interaction (MRI). The quality of experience of these services will be enhanced in terms of for example: spatial connectedness, by providing shared spaces and supporting spatial features such as eye contact; social connectedness, by using natural means for interaction suiting different settings and activities; and information connectedness, by providing better means to share, manipulate and use information suiting different task or activities. In this paper we will discuss the background of this work and give an overview of our planned future work in COMPEIT.

    Supporting automatic media resource selection using context-awareness2005Inngår i: The Third International Conference on Advances in Mobile Multimedia: (MoMM2005), September 19-21, 2005, Kuala Lumpur, Malaysia / [ed] G. Kotsis, Die Österreichische Computer Gesellschaft, 2005Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In a world of ubiquitous media resources, such as cameras, displays, microphones, provided by a wide variety of multimedia systems, there is a need for automatic resource selection which seamlessly utilizes the best available communication tool from a user perspective. This paper therefore presents an algorithm which uses context-awareness to support automatic media resource selection. The algorithm takes advantage of an abstract classification of privacy, quality, and cost in order to compare media resources to user’s preferences. As a proof of concept implementation, the algorithm has been incorporated into an e-meeting application called Marratech.

    An application-layer approach to seamless mobile multimedia communication2006Inngår i: IEEE Transactions on Network and Service Management, ISSN 1932-4537, E-ISSN 1932-4537, Vol. 3, nr 1, s. 33-42Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Providing seamless IP mobility support is one of the most challenging problems towards a world of mobile and ubiquitous multimedia communication. This paper proposes an application-layer framework based on the Session Initiation Protocol and the Resilient Mobile Socket to provide mobility support for distributed multimedia applications. As a part of the framework the paper describes a new handover strategy called Competition-based Soft-Handover Management that uses simulcast to improve quality of service and to seamlessly hand over multimedia traffic to the network interface that currently offers better network characteristics. In short, during a handover packets are simulcasted through all available network interfaces, and when the packets are received by the remote end-point, they are merged back into one stream. As each network connection competes with other connections in contributing to the merged stream at the remote end-point, the handover process can be viewed as a competition where the connection that contributes most is selected after the handover. As a proof of concept, the framework has been integrated into Marratech, which is a commercially available audio/video group communication application. By using network emulators, the paper demonstrates how the framework can be used to improve QoS, compare end-to-end performance, and perform lossless handovers while reducing redundant packets.

    Abstract [en]

    This paper presents an UDP-based socket extension called the resilient mobile socket (RMS), which provides application-layer mobility support by encapsulating other sockets into a new aggregated socket abstraction. Encapsulated sockets can then be added or removed without disturbing running applications. RMS also provides a method for soft handovers where several encapsulated sockets are used simultaneously during a handover. As a proof of concept, a working prototype has been built by integrating RMS with Marratech Pro, a commercially available e-meeting application. This prototype has been used to evaluate RMS and to investigate how GSM audio quality is affected by handovers. The result from the investigation shows that soft handovers can be executed without loosing packets or causing extra latency, while a hard handover in average took around 200 ms to complete. This indicates that proactive handovers and redundancy are important, but that more work must he done to predict disconnections.

    Mobility support for collaborative real-time applications2003Rapport (Annet vitenskapelig)
    Abstract [en]

    Today we are approaching a truly connected and wireless world where users can be always connected by switching between different carriers and providers. This paper presents an architecture which enables mobile media applications to operate across a wide range of wireless networks, gracefully handle network failures and share environmental information, such as packet loss-rate or available bandwidth with remote peers. The architecture is evaluated using a commercially available E-meeting application, Marratech Pro by seamlessly switching between three carriers; LAN, WLAN and GRPS.

Proceedings / [ed] John Vicente; David Hutchison, Berlin: Encyclopedia of Global Archaeology/Springer Verlag, 2004, s. 295-307Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As host mobility and radio interference in wireless networks cause packet losses and delays, it is difficult to develop useful mobile real-time media applications. This paper describes a new handover strategy for end-to-end mobility called Competition based Soft Handover Management (CSHM). During a handover, redundant packet streams are sent through multiple connections which are later merged into one stream when received by the other end-point. As each network connection competes with other connections in contributing to the merged packet stream, the handover process can be viewed as a competition. As a proof of concept, CSHM has been implemented in Resilient Mobile Socket, RMS, an application-layer mobility scheme and used together with Marratech Pro, which is a commercially available e-meeting application. By using this prototype, the paper shows that it is possible to minimize redundant packets as well as decrease packet losses during handovers.

    Abstract [en]

    This paper¹ presents a middleware that applies a micro-economic model to help multimedia applications utilize available bandwidth in a way that maximizes the user’s net benefit. The key components are a bandwidth broker that puts the supply of available bandwidth on a virtual market, and utility functions for each media, which are used to calculate the relative gain they can offer the user by using this bandwidth. Basic supply and demand principles are used where the broker raises the price if the total demand from all media exceeds the available supply, or lowers the price if the demand is lower than the available supply.

    Abstract [en]

    This paper presents an application-layer middleware that applies a microeconomic model to help multimedia applications utilize available bandwidth in a way that maximizes the user’s net benefit. The key components are a bandwidth broker that puts the supply of available bandwidth on a virtual market residing inside the application, and utility functions for each media, which are used to calculate their relative gain to the user at each bandwidth level. Basic supply and demand principles are used where the broker raises a virtual price if the total demand from all media exceeds the available supply, or lowers the price if demand is lower than the available supply. The advantage of the middleware is that it allows problems related to network management (usually affecting the supply) and human computer interaction (usually affecting demand) to be researched and integrated separately into an application and combined to leverage bandwidth in the best possible way. As a proof of concept, a prototype has been built by integrating the middleware into Marratech Pro, a commercially available e-meeting application. The paper presents experimental results using this prototype

    Abstract [en]

    An important part of making a wearable computer un-obtrusive is the user interface and the way it interrupts the user. The amount of interruption that have to be made on the users primary task should be minimized. Usage without interruption is of course best for the performance of the primary task but is often not possible as many tasks that the wearable computer is involved in do need interaction with the user. It is therefore important to understand what type of interruption that will benefit the user most. The question about which interruption that causes the least amount of stress for the user is as important as which interruption that gives the best performance. This paper continues on previous work where performance of the users was measured for different types of interruption. In this paper subjective data is analyzed to understand how to build user interfaces for wearable computers and head mounted displays that considers stress and other subjective variables.

    In the borderland between wearable computers and pervasive computing2003Rapport (Annet vitenskapelig)
    Abstract [en]

    In this paper we will show the ideas that are the foundation for the Borderland architecture. We have looked at two views of how researchers are thinking about computers in the future, wearable computers and pervasive computing. Wearable computers is the view where the user is wearing a computer and by that augment the user's view on his environment with additional digital information. Wearable computers have their strength in that they mostly do not have any requirements on the environment and that the user is in control of his integrity and security. In the pervasive computing view the digital representation of reality is in the physical environment itself. There are few requirements on the user for him to be able to use this digital augmented environment. There is also no restriction of what can be used in this environment as everything can be used for digital representation. We can see that the problems in one view are often the strengths in the other view. We believe that by combining these views into one we can use the strength of both areas and in that solve some of the problems involved in these two research areas. In this paper we present some of the problems we see in this combined view and also some ideas to solutions that we will evaluate in future work.

    Sharing experience and knowledge with wearable computers2004Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Wearable computer have mostly been looked on when used in isolation. But the wearable computer with Internet connection is a good tool for communication and for sharing knowledge and experience with other people. The unobtrusiveness of this type of equipment makes it easy to communicate at most type of locations and contexts. The wearable computer makes it easy to be a mediator of other people knowledge and becoming a knowledgeable user. This paper describes the experience gained from testing the wearable computer as a communication tool and being the knowledgeable user on different fairs.
